TEMPORARY BINDE.

Specification of Letters Patent. I

Patented May 29, 1917.

Application filed February 10, 1916. Serial No. 77,493.

To all whom it may concern:

Be it lmown that I, GEORGE P. \Vrecrn- TON, a citizen of the United States, residing in the city and county of Kalamazoo and State of Michigan, have invented certain new and useful Improvements in Temporary Binders, of which the following is a specification.

This invention relates to improvements in temporary binders.

My present invention is an adaptation and, in some respects, an improvement upon the mechanisms shown in Letters Patent No. 1,010,556, issued to me on the fifth day of December, 1911, and Letters Patent No. 1,022,452 issued to me on the ninth day of April, 1912.

The main object of my invention is to provide in a temporary binder or loose sheet holder an improved adjusting mechanism which is capable of rapid manipulation to permit the insertion or removal of the sheets or to secure the same, and one in which the sheets may be very securely retained although the mechanism is simple and compact and capable of embodiment in small binders.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which:

Figure I is an inside plan view of a binder embodying the features of my invention, one of the covers being broken away, the sheets being shown in an upright position.

Fig. 11 is a detail inverted view of the adjusting mechanism, with the holding pawl in engaging position and the adjusting pawl lever in a partially actuated position.

Fig. 111 is an inverted detail view of the adjusting mechanism showing the actuating lever in its initial position, the actuating pawl being disengaged when in such position.

Fig. TV is a detail inside view of a modified form of my invention in which the rack bar is supported for longitudinal adjustment, the binding members being connected to the rack bar.

Fig. V is a detail inverted view of the adjusting mechanism of the embodiment shown in Fig. IV.

In the drawing, similar reference characters refer to similar parts throughout the several views.

Referring to the drawing, 1 and 2 are the covers of the binder. The binding members 3 which in the structure shown are flexible strips extend between the covers. The binding members are secured to the cover 2 at 4: and adjustably connected to the cover 1 which is provided with a recess or chamber 5 for the adjusting mechanism.

The leaf or sheet clamping bars 6 are arranged substantially as shown in my Patent No. 1,022,452 referred to. The binding members 3 are connected to a cross bar or adjusting member 7 which is slidably mounted on the bar 8 disposed longitudinally in the chamber 5. This bar 8 is preferably a double rack bar, that is, provided with teeth on both sides. The adjusting member 7 is retained in its adjusted posi tions on the bar 8 by means of the holding pawl 9 which is mounted on the pivot 10 on the under side of the adjusting member. The holding pawl 9 is held yieldingly in engagement with the rack bar by means of the U-shaped spring 11, one end of which is supported by the pin 12 and the other end of which engages a notch 13 in the pawl. This spring is so positioned that it serves the double purpose of holding the pawl yieldingly in engagement with the rack and also of holding it in an inoperative position. The pawl is provided with a fin er piece 14 disposed through a segmental s 0t 15 in the adjusting member 7 so that it is conveniently accessible to permit the adjusting of the pawl to and from its inoperative positions.

The adjusting lever 16 is mounted on the pivot 17 on the adjusting member, the lever being disposed on the upper side of the ad- 'usting member 7. This lever carries a pawl pivot 18 disposed through the slot 19 and on which the lever pawl 20 is mounted so that it coacts with the rack bar 8.

The spring 21 is mounted on the pin 22 to engage the pawl 20 and serves to hold the pawl 20 yieldingly in engagement with the bar 8 and also to return the lever to its initial position. As the lever is swung to its initial position the pawl 20 engages the stop 23 and is lifted thereby from engagement with the rack so that when the lever is in its initial position the pawl 20 is disengaged from the bar.

By arranging the parts in this manner the pawl 20 is automatically disengaged and when the holding pawl 9 is disengaged the adjusting member slides freely on the bar. When the holding pawl is disengaged the binding members may be extended and the sheets engaged or disengaged therefrom, the sheets being slotted in the well known manner.

To look the binder the pawl 10 is shifted to its engaging position and the adjusting member drawn up, the pawl ratcheting over the teeth of the bar, or the adjusting member may be first drawn up and the pawl engaged to hold it in its adjusted position, as preferred by the operator.

To further tighten or add further stress to the binding member the lever 16 may be manipulated which adjusts the member 7 with a step by step movement.

In the modification shown in Figs. IV and V the adjusting member is in the form of a cross bar 25 to which the binding members are attached and the rack bar 26 is connected to the cross bar and disposed longitudinally of the cover. The bar26 is slidably mounted in the cross piece 27 secured'to the cover by the rivets 28. The holding pawl 9 and the adjusting lever 16 are mounted on this relatively fixed cross piece 27, the structure being substantially a reversal of the parts shown in Figs. IIII and it has many of the advantages of the embodiment shown in Figs. IIII, but requires more space for the same scope of adjustment.

I have not attempted to illustrate or describe certain modifications in the form of the holding pawland the adjusting pawl lever which I have developed and which might be desirable under certain conditions, as I believe the disclosure made will enable those skilled in the art to which my invention relates to embody or adapt my improvements as may be desired.

Having thus described my invention, what I claim as new and desire to secure'by Letters Patent, is:
